Disclosed is an external mounting type microchip dual band antenna assembly including a microchip dual band antenna connected to a printed circuit board which is disposed in a case of a portable terminal. The microchip dual band antenna comprises upper and lower patch elements respectively surrounding lengthwise upper and lower ends of a dielectric body having a shape of a quadrangular prism; a first radiation patch placed on a front surface of the dielectric body to extend zigzag from the upper patch element toward the lower patch element; a second radiation patch placed on a rear surface of the dielectric body to extend zigzag from the upper patch element toward the lower patch element in a manner such that zigzag configurations of the first and second radiation patches are staggered with each other; and a feeder channel defined on a side surface of the dielectric body adjacent to the lower patch element and plated in such a way as to connect the first and second radiation patches with each other.

External mounting type microchip dual band antenna assembly

Disclosed is a microchip dual band antenna mounted to a printed circuit board having a ground surface and a non-ground surface. The microchip dual band antenna comprises first and second patch elements respectively surrounding both lengthwise ends of a dielectric body having a shape of a quadrangular prism; a first radiation patch separated from the first patch element and placed on an upper surface of the dielectric body to extend zigzag toward the second patch element; a second radiation patch joined to the second patch element and placed on a lower surface of the dielectric body to extend zigzag toward the first patch element by a distance less than one half of an entire length of the dielectric body, in a manner such that zigzag configurations of the first and second radiation patches are staggered with each other; and a first feeder channel defined on a front surface and adjacent to one end of the dielectric body and plated in such a way as to connect the first and second radiation patches.

Microchip dual band antenna

Disclosed is a microstrip dual band antenna. The microstrip dual band antenna comprises a feeder hole defined in a widthwise middle portion adjacent to one end of a dielectric body which is formed in the shape of a quadrangular prism, a radiation patch line formed on an upper surface and on a portion of a lower surface of the dielectric body, such that it is placed around the feeder hole, extends through a first predetermined distance toward the other end of the dielectric body while having a first width corresponding to a diameter of the feeder hole, and extends through a second predetermined distance while surrounding the other end of the dielectric body and having a second width corresponding to a width of the dielectric body, a ground line formed on the lower surface of the dielectric body to be separated from the radiation patch line, such that it extends toward one end of the dielectric body while having the second width corresponding to the width of the dielectric body; a pair of strip lines formed on the lower surface of the dielectric body such that each of them substantially defines an L-shaped configuration and extends from a position separated from the feeder hole toward the other end of the dielectric body, and a pair of connection holes defined in the dielectric body at both sides of the feeder hole, respectively, and plated with suitable material.
